However, you can use "horrify" as a verb that relates to the adjective "horrible."
For example:
* The sight of the accident horrified me.
* The monster's appearance horrified the villagers.
You could also use "horrify" in the passive voice, which can be used to emphasize the action of something making someone feel horrible:
* I was horrified by the sight of the accident.
* The villagers were horrified by the monster's appearance.
